Application fil ed June so, 1924. Serial No. 723,227.

This invention relates to an improved rolling-device for use with cotton sample tables for rolling the cotton into paperwrapped bundles.

The principal object of the improvement is to provide means for expeditiously and 7 conveniently rolling the cotton samples into a bundle while wrapping a sheet of paper therearound and turning in flaps at the ends to hold the cotton in place.

, Another object of the invention is to pro- 'vide a device of the type specified which may be employed as an attachment for the usual sample display table or constructed as a permanent part ofv the tablelitself.

Another object of the invention is to I provide a device of the type specified which is simple in construction and economical to manufacture.

Further objects of the improvement are set forth in the following specification which describes a preferred embodiment of the invention as'illustrated in the accompanying drawings. In the drawings:

Fig. 1 is a perspective view of a cotton sample table showing my improved roll- I ing-device as applied to use therewith;

Fig. 2 is an end elevation of the. rollingdevice;

Fig. 3 is a plan view of the same;

Fig.4: is an end elevation illustrating a modified form of the device;

Fig. 5 is an enlarged end view ofone of the side-boards for the table showing it folded flat thereon; and y Fig. 6 is a view illustrating the manner in which the side-boards arearranged to guidethe flaps of the paper around the cotton.

Referring first to Fig: l' of the drawings, I have herein illustrated a cotton sample table 2 of conventional type having a relatively'low fiat top 3 supported from legs 4. At oneyen'd of the tablev 2 is a holderfor the-roll of wrapping paper comprising uprights 6 havingjbearings for the stick or At the opposite end of the table 2 is the bundle-rolling device indicated in general by the reference character 10. As herein illustrated the rolling-device is constructed separate from the table to be attached across the end thereof, but it is to be understood that it may be built into the table as a permanent part thereof. The rolling-device 10 consists essentially of a roller-box 11,

preferably constructed of wood, with its sides 12 of a length to adapt it to extend acrossthe full width of the table 2. When made separate from the table the rollerbox 11 is supported from two opposite legs or standards 13 formed by the end boards of the box. In this form the roller-box 11 is fastened to the table 2 by means of angleiron brackets 14 indicated in" Figs. land 3, or any other suitable attaching clamps or braces may be employed. 7

Adjacent the ends of the box 11 are cross strips or braces 15, seeFigs. 2 and 3, which provide bearing-supports for a pair of parallel rollers 16. The rollers 16 may have end-gudgeons 17 'journaled in suitable holes extending through the braces to mount the rollers in close parallel relation with their peripheries projecting slightly above the top 0 the boxas shown in Fig. 2.

Extending between the ends of the box and the cross-braces 15 are a series of parallel rods 19 betweenwhich are mounted two opposite arms or slides 20 adapted to slide -up and down while riding against theend boards or legs 13. The arms 20 are provided at the top with bearing holes 21 adapted to receive a horizontal cylindrical rod or roller 22 which serves as the spindle or mandrel around which the cotton and its wrapper is wound as indicated in Fig.

1. One end of the roller or mandrel 22 is 7 made square and fastened to a crank-handle 23, by means of which it may be rotated to wind the cotton therearound in the manner as hereinafter more fully explained, As

shown in Figs. 1 and 2, suitable w'eights'2t are fastened to the arms 20, at their lower ends whereby to draw them down tohold the 'roller'or mandrel 22 under tension with the package resting on the underrollers 1G to controlthe armsor slides 20 from a con-- tral weight 25 shown in Fig. 4: as ens pendedfrom cords'26. The cords 26; pass over pulley sheaves 27 within the boX 11 and hold the cotton in place.

thence lead through pulleys28 at the bottom of the legs 13 with their ends attached to the bottom of the arms 20. It Will be seen, therefore, that the weight tends to draw the arms downward and as the arms are raised with the increase in size of the package or bundle being wound onto the mandrel 22 the cords will be taken up' to raise the weight. I

Extending longitudinally of the top of the table 2 are two opposite folding sideboards 30 disposed a slight distancein from the edges of the top Referring toFigs. 5 and 6, a relatively narrow strip or rail 81 is screwed or otherwise fastened to the top 3 of the table at each side thereof with its outer edge beveled oit at an angle of forty-five degrees. A wider board 32 having a correspondingly beveled edge ishinged to the strip 31 33 to adapt it to fold upwardly at right-angles to the top of the table; while another still wider board 34 has its side hinged at 35 to'the top of the strip 32 with the meeting edges beveled. he hinges allow the boards to be, laid flat along the outer sides of the table when not in use, as shownin Fig. 6', while their beveled edges adapt them to be folded upwardly and inwardly as illustrated in Fig. 1 and shown by the dotted lines in Fig. 6 thus making a substantially inverted L shaped trough or guideway for directing the side flaps p of the strip of paper P across the edges of the layer of cotton spread across the paper.

Having now described the construction of my improved rolling-device in detail its method of operation will next be. eX- plained. The side-boards 30 are firstfolded flat against the top of the table, as illustrated in Fig. 6, and the sheet of paper P unrolled from the roll 5, shown in Fig. 1, and drawn forward toward the roller-box if). The cotton is now spread across the sheet of paper P and the sideboards folded upwardly and inwardly to turn the marginal flaps p of the paper over the edges of the layer of cotton. The leading end of the paper P is then fastened to the roller r mandrel 22 by doubling it therearound with its marginal flaps p folded mwardly, and usually the edge of the paper is moistened to make it adhere better to the roller. it being understood that the roller 22 is first inserted 'n place in its bearings 21 in the arms 20,

Now as the crank 23 is turned to rotate the roller 22 the latter will wind up the paper l and with it the cotton 6, forming a substantially cylindrical roll or bundle with the marginal flaps'of the paper strip guided by the side-boards 30 to turn or fold them into the ends of the" package to l 7 As the bundle builds up around the rod or' mandrel 22 with its under side restingupon and riding on the rollers 16 the mandrel 22 will. be

gradually'raised with the arms 20 sliding upwardly through the box 10. The weights 24 on the arms 2O act to resist the upward movement of the mandrel 22 and thus exert a pressure to hold the bundle against the under rollers 16 so that the cotton is compressed to form a firm, compact bundle with the paper wrapped snugly around" the layers in a spiral with its side flaps turned in at the ends to protect the cotton. Itwill be understood that the strip of paper P is severed from the roll in a length suflicient to enclose the layer of cotton with a. margin to cover the end thereof. full length of the strip has been rolled up in the manner above explained the crank 23 is given a short reverse turn to loosen the mandrel 22 from the end of the paper so that it may be drawn out from the center of the bundle after the latter has been tied with a cord wrapped therearound.

It will be observed from the foregoing that my invention provides a particularly simple and practical device for rolling up bundles of cotton samples. Suchsamples are used very generally for transporting and displaying different grades of cotton and are handled in large numbers by cotton brokers in purchasing and selhng the staple. It is usual "to spread the samples on display tables to exhibit them to buyers andwhere it is required to transport thesa mpl es to other locations the general practice is to roll them up in a sheet of Wrapping paper with flaps turned in at the ends to hold the cotton in place and with acord or rope tied on the outside of the bundle. In accordance with the usual practice of rolling the bundles entirely by hand it requires three men to roll a single bundle, one to rotate the mandrel andtwo more at the sides of the table to fold in the flaps that hold the cotton in place;

lVith the present improved device one man can expeditiously and conveniently rolL 11 the bundle in much less time than three men by the usual slow hand process and the completed bundles are more compact and uniform in size, so that they can be handled and stored to greater advantage. The reduction in the size of the Bundle for a given amount of cotton is quiteimportant because it is usual to store a large number of the bundles or packages in, ofliees and show-rooms where the space is valuable owing to high rents. My. improved device may be constructed as a permanent part of the sampletable or employed as an attachment thereto, and besides producing.

more uniform and compact bundles its use After the results in a considerable saving of time for combination with a cotton sample table of rolling the bundles. Moreover, the device is simple in construction and economical to manufacture and practically indestructible in use.

WVhile I have herein shown and described my invention in its preferred form it is to be understood that various modifications may be made in the structure and arrangement of the device without departing from the spirit or scope of the invention.

Therefore, without limiting myself to the exact embodiment illustrated, I claim 1. In a bundle-rolling device for cotton sample tables, the combination of a rotatable mandrel on which the bundle is rolled, rotatable rollers for supporting the bundle as it is rolled on the mandrel, means for mounting the mandrel to allow it to recede from the rollers as the bundleincreases in size while resisting its movement to cause the rollers to compact the bundle around the mandrel, and means to guide the paper wrapped around the bundle to fold its marginal portions into the ends thereof.
